Application filed June 24,

My invention relates ,to are lamps, and particularly to reflectors for arc lamps, and the principal object of my invention is to provide a new and improvedreflector particularly adapted for this purpose. Inthe drawings accompanying this specification and forming a partof this application, I have shown, for purposes of illustration,'one form which my invention may assume, and in these drawings: T

Figure 1 is a front elevation showing the embodiment of my invention herein illustrated,

Figure 2 is a section on the line 2-2 of Figure 1,-while Figure 3 is a section on the line 3-3 of Figure 1. v i

Herein I have shown my invention as ap plied'to an arc lamp 11 comprising an upper mechanism section 12 from which rise terminals 13 and 14, through which the entire lamp is supported by means of a hanger 15, and from which depend a pair of rods 16 supporting a frame 17 which carries on'its lower face an insulating disc 18 centrally apertured for the passage of the upper carbon 19 therethrough, is provided on its two sides with outwardly extending arms 20 provided at their ends with aperture'd lugs 21 adapted to receive insulating bushings 22 through which pass supporting and conducting rods 23 insulated from the frame 17 by means of the insulating bushings 22, held in position by means of nuts 24 flanking the insulating bushings 22, connected to a conductor 25 leading from one side of the line, surrounded by insulating tubes 26, and supporting at their lower ends a cross bracket 27 in which is mounted the lower carbon 28.

v The embodiment'of my inventionherein v shown comprises a reflector 30 formed in two parts, afront part 31, and av rear part 32.

The front reflector section 31 comprises a top 33, a base 34:, and a curved lateral wall 35 secured to the top 33 and the base 34, in-

terrupted centrally, and providedi at the edges of the interruption with projections 36 extending to engage the tubes 26 on the rear surface thereof'to maintain the reflector section 31 supported from the tubes 26 quickly removable therefrom because of the resiliency'of the 'extensions'36, extending then 'forwardly'about the tubes 26, and Ifinally terminating in lips 37; while the rear reflector section 32 comprises a lateral wall por- WILLIAM C.

tion 38 provided at its edges with lips 39- adapted to interengage the lips 37 ofthe tor section 31, and is provided at its lower end with an integral table 40 extending beneat h the arc to catch any material dropping from-the arc. e i

It will of course be; understood by those skilled in the art that thereflector sections 31 and 32 may be made conveniently by stamping; I V e 1 From the above description it will be obvious to those skilled in the art that I have provided a reflector particularly adapted for arc lamps, readily attachable and detachable, and economical to manufacture, and it therefore, will be apparent that the embodiment of my invention herein shown and described accomplishes at least the principal object of my invention, At the same time those skilled in the art will appreciate that the embodiment of my invention herein shown and described embodies advantages and uses other than those specifically set forth or suggested herein, and may be variously changed and modified without departing from the spirit of myrinvention or sacrificing these advantages and uses, and it therefore will be un derstood that the disclosure herein is illustrative only, and that my invention' is not limited thereto.

- I claim 1. A reflector for use with an arc lamp of a type having vertically extending members flanking the arc on'the two sides of thearc, comprising a top, a base,rand a lateral wall connecting said top and saidbase, and provided with resilient fingers adapted to resiliently, clamp said members to hold said re-v flector supported on said-lamp quickly detachable therefrom.
